The state of knowledge of the influence of atmospheric humidity on the moisture content of surface fuels in the open is discussed.

The author's experimental results indicate that prediction of fuel moisture based on atmospheric humidity varies throughout the day and night, that the degree of-association between relative humidity and fuel moisture is directly related to the rate of change of the relative humidity, and that relative humidity is a better indicator of fuel moisture than saturation deficit at all times, except possibly during the night.
